Abstract

Kenanga (Cananga odorata (Lam.) Hook.f. & Thomson) atau ylang- ylang dari famili Anonaceae merupakan salah satu tanaman kehutanan. Tujuan dari penelitian ini untuk mengetahui keanekaragaman dan kelimpahan serangga permukaan tanah di tegakan Kenanga (Cananga odorata (Lam.) Hook.f. & Thomson) yang diberi perlakuan pemupukan. Prosedur penelitian mencakup tahapan penentuan lokasi pengamatan, pengambilan sampel menggunakan metode pitfall trap, pengukuran faktor lingkungan, identifikasi serangga dan analisis data. Jumlah total fauna tanah pada perlakuan sebelum dipupuk ditemukan sebanyak 14 ordo dan 1421 individu sedangkan untuk perlakuan sesudah dipupuk ditemukan sebanyak 16 ordo dan 2108 individu. Setiap plot terjadi penambahan jumlah individu ketika sudah diberi perlakuan pupuk kecuali pada perlakuan pupuk. Faktor bertambahnya individu serangga tidak hanya dari pemberian pupuk namun dari faktor mikrohabitat, yaitu banyaknya serasah, tumbuhan bawah, suhu dan kelembaban. Morfospesies yang mengalami penambahan jumlah individu paling signifikan yaitu formicidae. Indeks keanekaragaman spesies semut yang relatif tinggi ditemukan pada plot kontrol. Kata kunci: Cananga odorata, keanekaragaman hayati, pupuk, serangga

Abstract

Bogor Botanical Garden (KRB) is an ex-situ plant conservation area with many plant types that dominated by tree. One of the family of trees collected in KRB is the Fabaceae family. This research aims to estimate the level of crown health condition in Fabaceae family in KRB using forest health monitoring (FHM) method. A total of 44 trees were observed using crown condition parameters to gain the visual crown rating (VCR), crown size index (CSI), and crown damaged index (CDI). This research showed that Fabaceae family in KRB reveal the VCR score of 6, indicated the medium health crown condition of tree. Thus, this research shows that most of the Fabaceae family’s tree at KRB are categorized in medium crown damaged rate. Keywords: Crown damaged index, crown health condition, crown size index, forest health monitoring, visual crown rating
